2014-09-12phy: miphy365x: Fix off-by-one errorLee Jones
We index the RX/TX speed select values in the following way: rx_tx_spd[miphy_phy->sata_gen]; However rx_tx_spd[] starts at index zero and the SATA_GENx's start at one. In this patch we pad out the first element in rx_tx_spd[] in an attempt to realign the values.

2014-08-24usb: phy: twl4030-usb: Fix lost interrupts after ID pin goes downTony Lindgren
Commit 249751f22380 ("usb: phy: twl4030-usb: poll for ID disconnect") added twl4030_id_workaround_work() to deal with lost interrupts after ID pin goes down. Looks like commit f1ddc24c9e33 ("usb: phy: twl4030-usb: remove *set_suspend* and *phy_init* ops") changed things around for the generic phy framework, and delayed work no longer got called except initially during boot. The PHY connect and disconnect interrupts for twl4030-usb are not working after disconnecting a USB-A cable from the board, and the deeper idle states for omap are blocked as the USB controller stays busy. The issue can be solved by calling delayed work from twl4030_usb_irq() when ID pin is down and the PHY is not asleep like we already do in twl4030_id_workaround_work(). But as both twl4030_usb_irq() and twl4030_id_workaround_work() already do pretty much the same thing, let's call twl4030_usb_irq() from twl4030_id_workaround_work() instead of adding some more duplicate code. We also must call sysfs_notify() only when we have an interrupt and not from the delayed work as notified by Grazvydas Ignotas <notasas@gmail.com>.

2014-08-24usb: phy: twl4030-usb: Fix regressions to runtime PM on omapsTony Lindgren
Commit 30a70b026b4cd ("usb: musb: fix obex in g_nokia.ko causing kernel panic") attempted to fix runtime PM handling for PHYs that are on the I2C bus. Commit 3063a12be2b0 ("usb: musb: fix PHY power on/off") then changed things around to enable of PHYs that rely on runtime PM. These changes however broke idling of the PHY and causes at least 100 mW extra power consumption on omaps, which is a lot with the idle power consumption being below 10 mW range on many devices. As calling phy_power_on/off from runtime PM calls in the USB causes complicated issues with I2C connected PHYs, let's just let the PHY do it's own runtime PM as needed. This leaves out the dependency between PHYs and USB controller drivers for runtime PM. Let's fix the regression for twl4030-usb by adding minimal runtime PM support. This allows idling the PHY on disconnect. Note that we are changing to use standard runtime PM handling for twl4030_phy_init() as that function just checks the state and does not initialize the PHY. The PHY won't get initialized until in twl4030_phy_power_on().

The phys array is of size EXYNOS_MIPI_PHYS_NUM. Trying to access the index EXYNOS_MIPI_PHYS_NUM should return an error.

2014-05-08phy: omap-usb2: Use generic clock names "wkupclk" and "refclk"Roger Quadros
As clocks might be named differently on multiple platforms, use a generic name in the driver and allow device tree node to specify the platform specific clock name.

2014-04-24phy: fix kernel oops in phy_lookup()Sergei Shtylyov
The kernel oopses in phy_lookup() due to 'phy->init_data' being NULL if we register PHYs from a device tree probing driver and then call phy_get() on a device that has no representation in the device tree (e.g. a PCI device). Checking the pointer before dereferening it and skipping an interation if it's NULL prevents this kernel oops.

2014-04-24phy: restore OMAP_CONTROL_PHY dependenciesJean Delvare
When OMAP_CONTROL_USB was renamed to OMAP_CONTROL_PHY (commit 14da699b), its dependencies were lost in the process. Nothing in the commit message indicates that this removal was intentional, so I think it was by accident and the dependencies should be restored.

2014-04-24phy: exynos: fix building as a moduleArnd Bergmann
The top-level phy-samsung-usb2 driver may be configured as a loadable module, which currently causes link errors because of the dependency on the exynos{5250,4x12,4210}_usb2_phy_config symbol. Solving this could be achieved by exporting these symbols, but as the SoC-specific parts of the driver are not currently built as modules, it seems better to just link everything into one module and avoid the need for the export.
